After a massively successful marketing stunt, 2 Chainz put the attention on a good cause.

Last month, rapper 2 Chainz decided to rent out a house in Atlanta, paint it a nice shade of Pepto-Bismol pink, scrawl the word “trap” across the front, and open it up to the public as a sort of ad hoc art installation you know, just normal stuff, as one does.

The whole thing was a marketing gimmick to promote his latest album, “Pretty Girls Like Trap Music,” and the project quickly took on a bit of a life of its own.

More than 1.1 million people in the U.S. are HIV-positive, and those who don’t know their status, are most likely to spread the virus. While there’s been a lot of progress in how we treat HIV/AIDS over the past several decades, it’s still a serious issue that needs attention.

By stepping up and making it easy to get tested, 2 Chainz is fighting the stigma that comes with an HIV diagnosis and helping prevent future outbreaks.

In the meantime, 2 Chainz’s Pink Trap House is open through July 7 (though there’s a chance it’ll be extended), so if you happen to be in the area, swing by, snap a few selfies, and let the world know you were there!
